A hybrid sterile locus leads to the linkage drag of interspecific hybrid progenies

Plant Diversity, 2020
Interspecific hybridization plays an important role in rice breeding by broadening access to desirable traits such as disease resistance and improving yields.

Patterns of sequence divergence and evolution of the S orthologous regions between Asian and African cultivated rice species. [PDF]

PLoS ONE, 2011
A strong postzygotic reproductive barrier separates the recently diverged Asian and African cultivated rice species, Oryza sativa and O. glaberrima. Recently a model of genetic incompatibilities between three adjacent loci: S(1)A, S(1) and S(1)B (called ...

Processes underpinning development and maintenance of diversity in rice in West Africa: evidence from combining morphological and molecular markers.

PLoS ONE, 2014
We assessed the interplay of artificial and natural selection in rice adaptation in low-input farming systems in West Africa. Using 20 morphological traits and 176 molecular markers, 182 farmer varieties of rice (Oryza spp.) from 6 West African countries

Termometria infravermelha na fenotipagem para resistência à seca de linhagens inter e intraespecíficas de arroz Infrared thermometry for drought phenotyping of inter and intra specific upland rice lines

Revista Brasileira de Engenharia Agrícola e Ambiental, 2010
Propôs-se avaliar, no presente estudo, a técnica da termometria ao infravermelho na caracterização de linhagens interespecíficas (Oryza glaberrima x Oryza sativa cv Caiapó) e intraespecíficas de arroz para tolerância a seca.

The complex geography of domestication of the African rice Oryza glaberrima. [PDF]

PLoS Genetics, 2019
While the domestication history of Asian rice has been extensively studied, details of the evolution of African rice remain elusive. The inner Niger delta has been suggested as the center of origin but molecular data to support this hypothesis is lacking.

Molecular characterization and genetic diversity of different genotypes of Oryza sativa and Oryza glaberrima

Electronic Journal of Biotechnology, 2017
Background: Availability of related rice species is critical for rice breeding and improvement. Two distinct species of domesticated rice exist in the genus Oryza: Oryza sativa (Asian rice) and Oryza glaberrima (African rice). New rice for Africa (NERICA)

Differential Salinity Tolerance among Oryza glaberrima, Oryza sativa and Their Interspecies Including NERICA

Plant Production Science, 2010
Salinity tolerance has been extensively studied in Oryza sativa, but little is known about the salt tolerance levels in Oryza glaberrima and the interspecific progenies including New Rice for Africa (NERICA).

Identification and Fine Mapping of Pi69(t), a New Gene Conferring Broad-Spectrum Resistance Against Magnaporthe oryzae From Oryza glaberrima Steud

Frontiers in Plant Science, 2020
The discovery and deployment of new broad-spectrum resistance (R) genes from cultivated rice and its wild relatives is a strategy to broaden the genetic basis of modern rice cultivars to combat rice blast disease.

Evaluation of Unconventional Supplements to the Diet of Intensively Reared Agouti (Dasyprocta leporina) in Trinidad, West Indies

Veterinary Sciences, 2020
A feed trial was carried out to evaluate potential unconventional feed resources such as Trichanthera gigantica and moruga hill rice (Oryza glaberrima) as a partial supplementation to the diet of adult male agoutis (Dasyprocta leporina).

BSA-seq Identifies a Major Locus on Chromosome 6 for Root-Knot Nematode (Meloidogyne graminicola) Resistance From Oryza glaberrima

Frontiers in Genetics, 2022
Root-knot nematode (Meloidogyne graminicola) is one of the emerging threats to rice production worldwide that causes substantial yield reductions. There is a progressive shift of the cropping system from traditional transplanting to direct-seeded water ...
